DL370 G6 with SAS p410i HpCISSs2 129

When testing the IO subsystem using SQLIO.exe tool every once in awhile we are able to hang the server and see the following errors in the error log:

Source: HpCISSs2EventID: 129The description for Event ID ( 129 ) in Source ( HpCISSs2 ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event: \Device\RaidPort0.

The error appears every 30 seconds.

When the error appears and we try to open the Array Configuration Utilities (or Array Diagonistics) they do not open up. The only way to get rid of the error is to hard-reboot the server.

Installed latest version of the RAID Controller driver (6.18.0.32) and of controller firmware (2.50).
